Description

Chemguard 3% AFFF-LT is a specially formulated, synthetic, aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket. It is intended for use at a proportioning rate of 3% (3 parts AFFF-LT concentrate to 97 parts water) on Class “B” hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. Chemguard 3% AFFF-LT is not intended for use on fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.

FEATURES

  • U.L. 162, Foam Liquid Concentrates
  • Suitable for use down to –20 degrees F
  • U. L. recommended topside application rate on hydrocarbon type fuels is .10/gpm ft².
  • Listing with JS-10 only
  • Suitable for use with either fresh or salt water
  • Excellent wetting characteristics when used in combating Class “A” fuel fires
  • Suitable for use with both aspirating foam and standard water fog nozzles
  • Suitable for use with deluge or closed head foam water sprinkler system

FOAMING PROPERTIES

Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% AFFF-LT is mixed with water at the correct ratio Non-aspirating type devices will typically generate expansion ratios or between 2-4 to 1. Expansion ratios are dictated by the type of discharge devices, flow rate and discharge pressure.
